Does't this just devolve into the boltzmann brain argument? It's more likely that all of us are just the random fluctuation of a universe having reached heat death. The same goes for us living in a simulation. If there is only one universe and that universe is capable of simulating our universe, it follows we have a much higher probability of being within the simulation.
